This frame member is 55 forward position.

also provided with a trigger guard Ib which extends around the trigger portion 8a of the trigger member 8, as shown best in Figs. 1 and 2 of the drawings. Extending downwardly and backwardly from the main horizontal portion of the frame member I is the handle member 6 which is hollow and shaped so as to receive the cartridge magazine 5, as shown best in Fig. 1 of the draw' ings. However, it will be noted that the cartridge magazine is not fully positioned inwardly in the handle member in Fig. 1 of the drawings. At the back side of the cartridge magazine 5 in the handle member 6 is a partition plate 6a which forms the back side of the cartridge magazine recess. This plate 6a. is provided with backwardly extending lugs 6b on opposite sides of the plate 6a between which is pivotally mounted the magazine catch 'I by means of a pin la. One portion of the member 'I extends from this pin 1a. downwardly and out through a slot 6c in the handle member 6 and is provided on its end with a curved member 'IbI which is knurled at its outer side to facilitate its movement. This member 'Ib extends forwardly and is'adapted to engage the lower end of the cartridge magazine 5 and hold'it in its proper position.`

The member 'I is in bellcrank form and therefore is provided with a rightangled portion 'IC which'serves as a support for the hammer bolt I9 and hammer bolt/spring I2, as shown best in Figs'. 1 and 2 of the drawings. The hammer bolt I9 is provided with a collar I9w and the spring I2 is positioned between the collar I9a and the member 'I c and tends to force the hammer bolt I9'upwardly at all times and to force the member 1c 'and therefore the catch member 'I into engagement with the cartridge magazine in the position shown best in Fig. 2 of the drawings. The upper end of this 'hammer bolt member I9 is rounded and adapted to fit into a recess 9a in the hammer member 9, as shown best in Fig. 7 of the drawings, when the hammer is in its backward position, and shown by dotted lines in Fig. 1 'of the drawings when the hammer is in its The handle member 6 is provided on opposite sides with hand grip members 6d and 6e for enclosing the sides thereof.

The cartridge -magazine is of the conventional form and is lshapedas shown best in' Fig. 15 of the drawings. It is provided with a spring 5a therein tending to force the cartridges upwardly in said magazine which cartridges are supported on the' supporting member 5b in superposed relation andthe upper member is provided with lspring portions 5c tending to hold the cartridges in their proper position as they are automatically' moved upwardly by the spring 5a as required for use.

VThe frame member I is provided with a longitudinal recess Ic in its upper side in which is adaptedl to reciprocate the trigger member 8, which trigger member is shown best in Figs. 3 and 4 of the drawings and consists of a frame 8b which is provided with a long slot 8c which is adapted to permit the upper end of the cartridgel magazine 5 to pass through the trigger member 8. Itis provided at its iront end with a downwardly depending trigger 8a which is rigidly secured thereto so that with the movement of the trigger 8a the trigger member 8 is reciprocated in the frame member I. This trigger member B is provided with a slot 8d at its forward end in which is mounted a pin 81e which extends into the frame on opposite sides and limits the movement of the trigger member 8 longitudinally in the recess in the frame. This trigger member 8 is also provided with another slot 8f through which passes a bolt 8g which extends into the frame member I at opposite sides of the trigger member 8 and also serves as the pivotal support for the hammer member 9. The bolt 8g also serves to support the sear member I which is provided with an extended portion I ila, shown best in Figs. 19 and 20 of the drawings, which is adapted to extend into a notch in the hammer member 9 and prevent its movement with the shifting of the trigger member in case the pistol is not in Iclosed operating position. This is shown best in Figs. 19 and 20 of the drawings.

The trigger4 member 8 is provided with a backwardly extending Aspring centering member 8h which extends backwardly into a hole Id and a spring I3 is positioned thereon which tends to force the trigger member 8 forwardly at all times.

This trigger member 8 is also provided with a slot 8i in its lower side,`as shown best in Fig. 3 of the drawings, ywhich is adapted to receive an inwardly extending pin IIa in the safety latch member VII when said latch member is in its upward position, said latch member being shown best in Fig. 14 of the drawings, thus preventing movement ofthe trigger member when the latch member II is in its upward position. This latch member II is also pvoted upon the bolt 8g and is provided with a detent portion I Ibwhich is adaptedto engage notches 4a and 4b respectively in the slide member 4, all as shown best in Fig. 14 of the drawings, for holding the slide member in certain position when desired.

The frame member I is also provided with an upwardly extending head portion Ie at its rear end in the lower side of which is pivotally mountedthe breaking catch member I8 which is provided with an outwardly extending knurled portion Ida and with an inwardly extended forwardly turned portion Ib which is adapted to engage the lug 87' on the trigger member 8 and prevent the trigger member from coming backwardly when the breaking catch is released so that the pistol may be broken, all as shown best in Fig. of the drawings.

The frame member I is also provided with a centering recess If which is adapted to receive a lug`2b depending from the rear end of the frame member 2. A

The frame member 2 is pivotally mounted relatively to the frame member I as heretofore stated by means of the bolt 20 through the lug 2a of the member 2 thus providing means for breaking the members I and 2. The frame member 2 is provided at its front end with the barrel 3 which is the conventional rifle barrel. Itis provided near its front end at the upper side with a sighter member 3a. and just in front of the sight member and slightly back of the muzzle end of the barrel is a slot 3by which extends downwardly into the barrel some distance. This slot is for the purpose of providing a means to compensate for the pressure on the upper side of the barrel to prevent the kick-up of the muzzle end of the piston. It will be noted that the back end of the barrel 3c is rigidly secured in position in the front portion of the member 2. This'frame member then extends backwardly in reduced height and is provided in opposite sides with slots 2c which aline with slots Ik in the member I, as shown best in Fig. 18of the drawings.

The frame member 2 is also provided with a notoh2d in its rear end upwardly from the lower side and adjacent the lug 2b which is adapted to receive the portion I8c of the member I8 when the knurled portion is in its forward position for holding the members I and 2 in closed relation to each other.

Shiftably mounted longitudinally on the frame members I and 2 and supported thereon by means of inwardly extending rib members 4o on the member 4 engaging the slots 2C of the member 2 and Ik of the member I is the slide member 4. This slide member i is adapted to reciprocate backwardly and forwardly with the operation of the pistol. This slide member 4 is provided with a bore ld in which is reciprocally mounted the firing pin I5, shown best in Fig. 2 of the drawlngs.

This firing pin I5 is provided with a head Ia which is adapted to be engaged by the hammer 9 when released by the trigger member 8 and between the head Ia and a shoulder 4e in the member 13 is interposed a spring I6 tending to hold the firing pin backwardly. The other end of the firing pin I5 is provided with a tapered end which is adapted to engage the cartridge when ring the pistol. This ring pin is provided with an enlarged portion I5?) intermediate its ends which serves as a stop to limit the reciprocal movement of the firing pin I5 which engages a shoulder in the member 4 at one end and a screw in the member 4 at the opposite end. This member 4 is also provided with another bore 4f in which is mounted the retractor and recoil spring I 4. This spring I@ surrounds an ejector member Idal which. is in the form of a pin mounted inside of the coil spring I4 and is provided with a reduced portion Ilib which is adapted to pass into and through the reduced portion 4g of the bore 4f and eng-age the side of the cartridge for ejecting the same when the slide member 4 is in its backward position caused by the recoil from the explosion of the cartridge in ring. This pin Ilia. is provided with a head member Ic at its rear end which is shaped as shown best in Figs. 10 and 11 of the drawings, which is provided with a notch Idd in the member Ido which provides a shoulder for engagement with the lug Im for supporting the free end of the member Ia laterally. 'I'his free end is also provided with a rounded portion which engages a rounded recess I n in the member I, shown best in Fig. 6 of the drawings. The shoulder de is adapted to engage the hammer for moving it backwardly with the backward movement of the slide member 4 for positioning it in the position shown by solid lines in Fig. 2 of thel drawings ready for ring again.

Mounted in the forward end of the member d pivoted on the pin IIa is the cartridge extractor member I'I which is provided with a hook portion Hb which is adapted to engage the forward side of the rim of the cartridge, as shown best in Fig. 12 of the drawings, for drawing the exploded cartridge backwardly with the backward movement of the member 4, and it is supported in its engaging relation by means of a pin I'IC backed by a spring Ild both of which are in a recess in the member d, all shown best in Fig. 12 of the drawings.

The slide member i is also provided with a pair of grooves ih into which the upper edge 5c of the cartridge magazine extends when inserted in position.

This member 4 is also provided near its back end at its upper side with a sight member 2| 4,which extends upwardly above the upper surface of said member I which sight member is of the conventional form.

The operation of my automatic pistol is as follows: The magazine 5 is inserted in position as shown in Fig. 2 of the drawings, and while it is being inserted the catch member I is moved backwardly, as shown in Fig. 1 of the drawings, slightly compressing the spring I2. When the magazine is fully inserted the member 'I is forced backwardly by the spring I2 to the position shown in Fig. 2 of the drawings, thus providing means forsupporting the magazine rigidly in position. Thus it will be noted that this spring I2 serves` both for operating the catch I and for operating the hammer bolt I9. It will be noted that the uppermost cartridge in the magazine rests on the ridge between the grooves 4h, shown best in Fig. 8 of the drawings. The slide member i is now drawn once to the rear by hand, thereby cooking the hammer S. In this position of the slide member the magazine spring 5a raises the topmost cartridge so as to bring it into the path of the slide I and upon releasing the slide it is carried with the slide by the retractor spring and during this movement the slide forces the topmost cartridge into the barrel 3. As the slide approaches its forward position the front of the slide encounters the rear end of the barrel and forces the cartridge in position and the pistol is ready for ring.

A slight pull on the trigger now serves to move the sear so as to release the hammer and fire the shot. The force of the powder gases driving the bullet from the barrel is exerted rearwardly against the slide overcoming the inertia of the slide and the tension of the retractor spring causes the slide to move backwardly. After mov ing backw-ardly for a distance far enough to insure the bullet having passed from the barrel its momentum causes it to continue its rearward movement thereby again cooking the hammer and compressing the retractor spring until as the slide arrives at its rearmost position the empty shell is ejected from the side of the pistol and another cartridge raised in front of the slide. During the return or forward movement of the slide caused by the retractor spring the cartridge is driven into the barrel thus making the pistol ready for another shot. These operations may be continued so long as there are cartridges in the magazine, each discharge requiring only the slight pull on the trigger.

t will be noted that in applicants structure the retractor spring I serves as a retractor as well as an ejector of the spent cartridge; that the pistol is so constructed that it will not nre until in closed, locked and spaced position; that the hammer spring also serves for the magazine catch spring.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims,
